Objective: To determine the suitable ecological habitats of Aedes (Ae.) aegypti and Ae. albopictus in Iran due to climate change by the 2070s. Methods: All data relating to the spatial distribution of Ae. aegypti and Ae. albopictus worldwide, which indicated the geographical coordinates of the collection sites of these mosquitoes, were extracted from online scientific websites and entered into an Excel file. The effect of climatic and environmental variables on these mosquitoes was evaluated using the MaxEnt model in the current and future climatic conditions in the 2030s, 2050s, and 2070s. Results: The most suitable areas for the establishment of Ae. aegypti are located in the southern and northern coastal areas of Iran, based on the model outputs. The modelling result for suitable ecological niches of Ae. albopictus shows that in the current climatic conditions, the southern half of Iran from east to west, and parts of the northern coasts are prone to the presence of this species. In the future, some regions, such as Gilan and Golestan provinces, will have more potential to exist/establish Ae. albopictus. Also, according to the different climate change scenarios, suitable habitats for this species will gradually change to the northwest and west of the country. The temperature of the wettest season of the year (Bio8) and average annual temperature (Bio1) were the most effective factors in predicting the model for Ae. aegypti and Ae. albopictus, respectively. Conclusions: It is required to focus on entomological studies using different collection methods in the vulnerable areas of Iran. The future modelling results can also be used for long-term planning to prevent the entry and establishment of these invasive Aedes vectors in the country.

Objective: Different studies have been performed on the prevalence of tick-borne pathogens in different areas of Iran; however, as far as our knowledge, there is no regional meta-analysis available for consideration and estimation of tick species infected with different pathogens in Iran. Methods: In this review, among different databases, a total of 95 publications were included, and the infection of different tick species to different tick-borne pathogens was determined; furthermore, presence of pathogens (with 95% confidence intervals) in tick vectors was calculated separately for each province, using Comprehensive Meta-Analysis version 2 (Biostat, USA). Results: Totally, among all 95 studies, 5 673 out of 33 521 investigated ticks were positive according to different detection methods. Overall estimated presence of pathogens in tick vectors in Iran was 8.6% (95% CI 7.0%-10.6%, P 0.001). Of all 46 species of ticks in 10 genera in Iran, 28 species in 9 genera, including Alveonasus, Argas, Boophilus, Dermacentor, Haemaphysalis, Hyalomma, Ixodes, Ornithodoros, and Rhipicephalus were infected with at least 20 pathogens in 10 genera including Aegyptianella, Anaplasma, Babesia, Borrelia, Brucella, Orthonairovirus [CrimeanCongo hemorrhagic fever virus (CCHFV)], Coxiella, Ehrlichia, Rickettsia and Theileria in 26 provinces of Iran. The presence of pathogens in ticks collected in western Iran was more than other regions. Hyalomma anatolicum (20.35%), Rhipicephalus sanguineus (15.00%), and Rhipicephalus bursa (14.08%) were the most prevalent infected ticks for different pathogens. In addition, most literatures were related to CCHFV and Theileria/Babesia spp. Conclusions: Public health and veterinary professionals should be aware of diagnosing possible diseases or outbreaks in vertebrates.

Objective: To estimate the infection of ticks to Anaplasma, Ehrlichia, Babesia, Theileria, and Brucellaceae using molecular methods in borderline of Iran, Azerbaijan, and Armenia. Methods: Totally, 2 022 ticks were collected from different livestock. Then, species were diagnosed under stereomicroscope according to valid morphological keys. Tick DNA was extracted followed by PCR to detect Anaplasma, Ehrlichia, Theileria, Babesia and Brucellaceae infection in ticks. Results: A total of 498 males [24.62% (95% CI 22.76%-26.57%)], 741 females [36.64% (95% CI 34.54%-38.79%)], 782 nymphs [38.67% (95% CI 36.55%-40.84%)] and 1 larva [0.04% (95% CI 0.00%-0.28%)] were identified. Among identified samples, we found four genera including Hyalomma, Rhipicephalus, Haemaphysalis, and Dermacentor. Molecular assay revealed that the prevalence of ticks to Anaplasma or Ehrlichia, and Brucellaceae was 22.02% (95% CI 16.01%-29.06%) and 15.03% (95% CI 9.43%-22.26%), respectively. Phylogenetic analysis showed that the identified Anaplasma sp. had the most similarity with Anaplasma centrale, Anaplasma platys, Anaplasma camelii, and Anaplasma phagocytophilum, submitted in GenBank. Furthermore, the detected Ehrlichia sp. and Brucellaceae bacterium had the most similarity with Ehrlichia ruminantium and Mycoplana peli, respectively. However, no sign of the presence of Theileria and Babesia spp. was seen in the studied samples. Conclusions: Anaplasmosis, ehrlichiosis and brucellosis should be considered as important health threats in northwestern Iran and consistent monitoring on infection of ticks and livestock should be performed regularly.

Objective: To evaluate the susceptibility of Anopheles stephensi (An. stephensi) Liston, the main malaria vector in southern Iran, to WHO recommended insecticides. Methods: Larvae of An. stephensi were collected from three different larval habitats in both urban and rural area of Bandar Abbas city and one rural area in Rudan county southern Iran. WHO standard method was used for evaluation of adult and larval mosquito susceptibility. Bendiocarb, permethrin, lambda-cyhalothrin, deltamethrin as insecticide and temephos and chlorpyriphos as larvicide were used at the diagnostic dosages recommended by WHO. Results: Findings of this study showed all larval populations of An. stephensi were completely susceptible to temephos and candidate for resistance to chlorpyriphos. Adult mosquitoes in rural areas of Bandar Abbas city were resistant to pyrethroid and carbamate insecticides. Conclusion: Comparison of the results of this survey with previous studies indicates that the resistance to pyrethroids and carbamates in this malaria endemic region is increasing. Wide use of pesticides in agriculture is certainly effective in increasing resistance. The inter-sectoral coordination and collaboration in health and agriculture seem to be necessary to manage insecticide resistance in malaria vectors.

BACKGROUND: This is the first study on the blood donation trend in Iran at a national level. We report different characteristics of blood donation such as demographic status, donor type, donation trend, and geographical distribution of blood donation in Iran between 2003 and 2017.METHODS: This study used data registered in the donor vigilance part of the Iranian Blood Transfusion Organization. Statistical analysis was conducted using SPSS (SPSS Inc., Chicago, IL, USA) and ArcMap GIS version 10.2 software. A P-value <0.05 was considered statistically significant.RESULTS: Based on the study results, blood donation in Iran reached >2 million units in 2017; moreover, it is predicted that Iran will achieve >29 donations per 1,000 population in 2022. The proportion of regular and repeated donors increased from 77% in 2013 to 87% in 2017. The average blood donation rate in seven provinces was higher than the national average, and the average growth rate of their blood donation per population was positive.CONCLUSION: The results of the current study showed that there is a recent increasing trend toward blood donation in Iran. Furthermore, the largest share of donations is related to regular donors. The increasing proportion of regular and repeated donors has led to the improvement in the quality and consequently health level of donated blood.

OBJECTIVETo study agents of animal wound myiasis in various geographical districts of Fars province.

METHODSThis study has been done in Fars province, located in the southern part of Iran. Sums of 10 358 domestic animals have been visited from April 2011 to March 2012. The infected wounds in any parts of animal body were sampled by means of forceps.

RESULTSAbout 61% of all animal wound myiasis were caused by larvae of Wohlfahrtia magnifica. The most wound myiasis cases due to this species occurred in central part of Fars province. There wasn't any significant difference between sheep and goat in infestation with myiasis (P>0.05). The infestation rate of myiasis in cattle community was 0.86%.

CONCLUSIONSThe infestation rate of livestock was lower than other works in Iran and some other countries like Saudi Arabia. Chrysomya bezziana has been mentioned as main myiasis agent in Iran. But in this study it cleared that similarly to some European countries, the common animal myiasis agent in Iran is Wohlfahrtia magnifica. Introducing new species as principal agent for myiasis can help public health and animal husbandry policy makers to prepare sufficient and effective control and/or preventive measures for this disease.

OBJECTIVETo determine the prevalence of ticks on cattle in the mountainous areas of Golestan province and their geographical distribution.

METHODSIn total, 498 animals from 25 herds were selected to search for ticks in 2009-2010. Tick collection was carried out during four seasons, twice per season over a period of 12 month from March 2009 through February 2010 in two districts, Azadshahr and Ramian. Meteorological data were obtained from Iran Meteorological Organization. The geographical points recorded using a Garmin eTrex®H GPS.

RESULTSA total of 255 ticks were collected from a total of 219 ruminants including 44 sheep, 63 goats, 99 cows and 13 camels in two districts of the mountainous area of Golestan province, including Azadshahr and Ramian. Five species of ixodid ticks were identified: Rhipicephalus sanguineus (66.5%), Rhipicephalus bursa (4.6%), Hyalomma marginatum (19.9%), Hyalomma anatolicum (6%) and Hyalomma asiaticum (4%). The densities of infestations were calculated for sheep, goats, cows and camels 0.9, 0.79, 0.16 and 0.43 respectively. Seasonal activity of each ixodid tick infesting domestic ruminants was determined. The distribution maps showed ixodid ticks on domestic ruminants, and Rhipicephalus sanguineus were dominant species in the area.

CONCLUSIONSSuch research provides necessary information for human and animal health service mangers to have a better understanding of prevention and control of vector borne diseases especially during the outbreaks.

OBJECTIVESince appropriate and time-table methods in trauma care have an important impact on patients'outcome, we evaluated the effect of Advanced Trauma Life Support (ATLS) program on medical interns' performance in simulated trauma patient management.

METHODSA descriptive and analytical study before and after the training was conducted on 24 randomly selected undergraduate medical interns from Imam Reza Hospital in Mashhad, Iran. On the first day, we assessed interns' clinical knowledge and their practical skill performance in confronting simulated trauma patients. After 2 days of ATLS training, we performed the same study and evaluated their score again on the fourth day. The two findings, pre- and post- ATLS periods, were compared through SPSS version 15.0 software. P values less than 0.05 were considered statistically significant.

RESULTSOur findings showed that interns'ability in all the three tasks improved after the training course. On the fourth day after training, there was a statistically significant increase in interns' clinical knowledge of ATLS procedures, the sequence of procedures and skill performance in trauma situations (P less than 0.001, P equal to 0.016 and P equal to 0.01 respectively).

CONCLUSIONATLS course has an important role in increasing clinical knowledge and practical skill performance of trauma care in medical interns.
